Answer 1

$86 was in Maya's account before she started to deposit money.

Explanation:

Your first step is to calculate how much she is depositing each month.

(8th month) $606 - (6th month) $476 = 130

Since $476 and $606 is a two month difference, you need to divide 130 by 2.

130 / 2 = 65

From here, you multiply your quotient by the least amount of months Maya was depositing money, in this case 6.

65 * 6 = 390

Subtract $390 from $476 (month 6)

$476 = $390 = $86

Answer 2

Explanation:

a) Subtract until you get to one 1 in time(months)
